@gis_sweden: Thanks :) Maybe I spelled it wrong, sorry. It could be Micrologic. I think it is a smaller software-version of Logic (not sure). It's a midi only software-sequencer from the nineties. I used it on an old Apple Macintosh Performa (with 150MB hard-drive :) in combination with the external sound module MU80 from Yamaha and a midi-synthesizer. I don't make this kind of midi-music anymore though... :S
